: Seems like we have our system react similarly now. But I can have CnQ enabled and get normal boosting behaviour. The results seem the same though.
7nm is definitely a funky beast with the voltages.
I still haven't touched any of the OC dials because it seems pretty much maxed out already and I'm waiting for another BIOS update or two and some more experiences from actual people and not just the LN2 youtube crowd.
Dialing in my RAM though. Bought some 2x16GB HyperX Kingston 3200C18 from Amazon, since they were available for next day delivery, cheap (175€) and seemed like decent overclockers at 3200 CL18 with 1.2V, even got a Micron E-die kit. Hoping for the DRAM calculator tomorrow with Zen2 support. So far I'm at 3600 MHz, CL16, 18, 22, 19. tRAS 37, TRC 62, tRFC 556 and the rest on auto with suboptimal timings, Voltag is 1.37V. ProcODT 53.3 ohm, RttNom disabled, RttWr 80 ohm and RttPark 240 ohm and can't budge (no startup). Got those settings from the current DRAM Calc and some screenshots. I envy those 3600C14 people, but I guess they paid an arm a leg for the RAM. I'd rather have 32GB with some looser timings myself.
I'm really happy I modded the IO plate with a clear CMOS button.
And it's really crappy that the B450M Mortar lite BIOS does not have save profiles (maybe implement it with a USB stick?) and it doesn't recover from wrong RAM settings like other, more OC oriented boards I've used in the past where they loaded defaults when it didn't start up for a few tries. Oh well, the failing of mATX. Btw those settings still aren't rock solid, getting errors in Karhu RAM Test at about 1000%. Using that before switching to HCI Memtest pro because it seems a bit faster so far. Currently playing with SoC and VDDP/VDDG voltages. If everything fails I'll dial it back down to 3533 MHz and see what timings I can run. This is more testing for an overclock than I had to do since the i7-860 with base clock overclocking. That things destroyed my windows install a few times, that hasn't happened so far.
